FAQ
-
Which target material is optimal for calibration?
Factory calibration is done for AISI 4140 steel; other ferromagnetic materials may require recalibration. -
What is the maximum cable extension supported?
Extensions up to 9 meters are supported when paired with a compatible proximitor. -
Can this probe be used in hazardous environments?
Yes, it meets ATEX and CE Zone 1 requirements when installed with certified accessories. -
How does temperature variation affect measurement accuracy?
Integrated temperature compensation minimizes signal drift across the full operating range. -
What is the typical output sensitivity when connected to a proximitor?
Standard output is 200 mV per mil (7.87 V/mm) with ±5% tolerance. -
Does the probe provide both dynamic vibration and static shaft position measurements?
Yes, it delivers simultaneous vibration and displacement signals. -
What is the minimum recommended bend radius during installation?
A minimum bend radius sur 25 mm is recommended to maintain cable integrity. -
Is periodic recalibration required?
Calibration is generally only necessary after major system reconfiguration or component replacement. -
Is the probe shielded against electromagnetic interference (EMI)?
Yes, coaxial cable and internal shielding provide excellent EMI resistance. -
Is it compatible with older Bently Nevada monitoring systems?
Yes, when used with the correct proximitor and calibration procedures.
